Answer:
The area of the dilated square is 28 m^2
Step-by-step explanation:
we know that whenever any figure is dilated by a factor 'b' units
so, area will be dilated by b^2 units
Here , we are given figure is dilated by 7 units
so, area will be dilated by 7^2
we are given
Area of square is

now, we can multiply by 7^2
and we will get area as


So,
The area of the dilated square is 28 m^2
The answer is 30.
( See picture for equations )
4 × y - y = 36
4y - y = 36
Combining 4y and -y to get 3y
3y = 36
Dividing both sides by 3
y = 36/3
y = 12.
